Still having issues getting NextCloud installed - "Can’t create or write into the data directory opt/nextcloud/data”

Okay… Like I said… I’m making progress.

I just re-checked NGINX error log and see the following:

open() “/var/www/html/nextcloud/data/htaccesstest.txt” failed (2: No such file or directory), client: 192.168.1.1, server: subdomain.domain.dom, request: “GET /data/htaccesstest.txt HTTP/1.1”

Shouldn’t it be trying to get this file from /opt/nextcloud/data ?
Where do I change this?
